Subject: [PATCH] [IMP] app: expose live apps for the devtools

This commit exposes owl apps in a global variable so that the owl
devtools can hook themselves on these apps. While the devtools are not
yet ready to be merged, exposing the apps will allow us to test the
devtools in production scenarios while polishing the development of
them.
